Summary: Sam and Dean come across a case involving several disappearances and a lake. Now it's up to them to save the victims and try to stay alive, which is easier said than done. While trying to solve the case and figure out what monster is wreaking havoc, Sam is attacked and nearly drowns...

Sam was lost in thoughts, absentmindedly playing with his bottle of beer.
Dean was at another table, talking and flirting with some blonde. But Sam couldn't focus on having fun tonight, because he'd noticed something on the way to the shitty bar in the small town they were in, that his big brother hadn't. Three different missing people posters. He didn't know if it was just a coincidence, nothing really suggested that something supernatural was going on, except for the feeling in his gut. He just knew they couldn't move on from this town yet.
Impatiently he waited for his brother to be done, barely touching his beer, and then they started heading back to the motel they were staying at. On their way therethough, Sam noticed another one. Another missing person poster, a new girl.

"Dean, hold on", Sam said, confounded. "There's something here."
"Huh?" Dean slurred, slightly drunk. "Wha'd'ya mean?"
Sam was studying the poster. "I think there's a case here. This is the fourth missing person I've seen in this town."
"So?" Dean clearly hadn't caught on yet.
"So, I think that's a lot of people for a small town like this one. Something's going on here."
"Alright. So… we'll check it out tomorrow", Dean said with a yawn. "I wanna go back'n'sleep now."
Dean gave his younger brother a slight push forward to get him moving again, and Sam reluctantly obeyed, knowing they wouldn't get anything done tonight anyway.

The next morning, Sam woke up early, eager to get started. He took a quick shower while waiting for Dean to wake up. Seeing as his brother was still asleep when he got out, he decided to go for some breakfast too and picked up coffee and sandwiches. He got back to the motel and found that Dean was still sleeping.
"Hey, wake up, dude", Sam said, nudging his brother's leg.
Dean groaned and rolled over, squinting up at Sam.

"What time is it?" He mumbled.
"Eight", Sam replied, sipping his coffee. "Time to get started on this case."
With a yawn, Dean sat up on his bed and rubbed his eyes. Muttering something that sounded like "too early, man", he then stumbled out of bed and into the bathroom, closing the door loudly.
Sam gave a chuckle before starting in on his breakfast.

The police department was located in a small building made out of dirty-looking gray bricks. Sam and Dean walked in with their FBI badges at the ready. The place was crawling with cardboard boxes, like they'd just moved there in a haste.
"Hi", Sam said when they got to the reception, showing his badge. "Agent Moseley. This is my partner, agent Squill."

Dean held up his badge.
"We're here about the recent disappearances", Sam continued. "We'd like to see the case files."
The guy at the reception studied their badges for a moment, and then he shifted his attention to their faces. Sam made sure to keep his expression calm and stern.
"Alright then", the guy sighed. He pushed a couple of buttons on the computer and printed out a piece of paper.
Moments later a police officer walked into the room. The receptionist handed him the paper. A name tag on his shirt read; Officer Donovan.
"Follow me", Donovan said in a low voice.
He guided them through a white, brightly lit hallway, to a black metal door with big white letters on it spelling "RECORDS". Donovan held a card to the scanner next to the door, pushed in a code and then used a key to open the door.

No matter how unorganized the place looked, Sam had to admit that the security system definitely was thorough.
They walked into the file room, which was crowded. Every wall was covered in shelves filled with boxes containing files. Sam had no idea how they were even able to orientate through the maze of shelves.
Donovan looked down at the list on his paper and then moved knowingly through the room, quickly locating the files that were needed.
"These are the files on Sophie Cooper, Amanda Hibbing, Natalie Eden and Mona Thorne." The policeman handed them over to Sam, who gave half to Dean.
"Have you noticed anything that the victims have in common?" Dean asked.
"Well, obviously they were all girls. Different ages though, different origins. We haven't really found anything else that connects them yet."
"Thank you, sir", Sam said. "Please let us know if anything new comes up."
He handed him one of his FBI cards with their phone number on it. Donovan took it with a short nod.

Hours later, Sam and Dean were back in their motel room, reading through the thick files over and over again for some clue. Dean was just about ready to give up.
"I'm telling you, man, maybe there's nothing supernatural going on here", Dean said, rubbing a hand across his face. His eyes were tired from all the reading. "They seem like ordinary disappearances, you know, teenagers running off."
Sam shook his head, keeping his eyes on the files he was flicking through. "No, there's something here. I know it. There has to be."
Dean sighed, but the expression on his brother's face told him it wasn't up for discussion. Then, it suddenly changed, frustration turning into excitement.
"Wait, I found something", Sam said eagerly. "Sophie Cooper and Amanda Hibbing were camping together in the woods, right, and no one's seen them since?"
Dean nodded. "Yeah?"
"So, they were camping near the lake. And Natalie Eden, she was at the same lake, swimming with her brother."
Realization hit Dean, and he suddenly knew where this was going. "Let me guess, Mona Thorne was also around that lake when she disappeared?"
Sam nodded, a small smile on his lips. "Yeah, she was fishing with her boyfriend."
"Okay, so what does that mean?"
Sam bit his lip. "Don't know yet. But I'll bet my life that it has something to do with that lake."
That's when the phone suddenly rang. Sam picked it up with raised brows. "It's the police station."
He pressed the answer button, holding the phone to his ear.
"Agent Moseley. Yes. Uh huh. Really? Wow. That is strange. Yeah. Thanks for letting us know. Bye."
He hung up the phone with wide eyes.
"What?" Dean asked. "What did they say?"
"That was, um, officer Rebecca Ridley. She... She said that they'd found a body, and she'd been told to let us know."
"A body? Who?"
"Sophie Cooper. Guess where they found her?" Sam said with a pointed look.
Dean didn't even have to guess. "The lake."
Sam nodded. "The cause of death was drowning. But that's not even the strangest part. They found deep claw marks on her back. They were long, too. Like something dug it's claws into her back and pulled down."
"Jeez. Well, I guess that confirms that there is something for us here."
"Yeah. Maybe it's time we head out there to do some investigating. But first, we got some research to do." Sam smiled.
Dean shook his head at Sam who seemed really excited about the fact that hey were going to be doing research for the next couple of hours. He himself really dreaded it.

"There's nothing here!" Sam exclaimed, annoyed. He shut his computer with a smack. "There are about a hundred water creatures that could be taking them." He pulled a hand through his hair in frustration. "What about you, find anything?"
Dean shook his head. "No, I didn't really find anything either."
Sam sighed. "Alright, let's just head out to the lake then."
"Great, first research and now we gotta hike through the woods", Dean said sarcastically. "Could it get any better."
